To u? whom it may concern:

Be it knovm that. I. Joux P. Douala, a of the United States, and resident of Jeerson, in the county of Jefferson and State of Wisconsin, have invented new and useful Improvements in Driving Mechanism, of which the following is a description, reference being had to the accompany-ing drawings, which are a part of this specifi cation.

The invention relates to driving mechanisln, and more particularly to a driving mechanisn for a washing machine.

It is one of the objects of the present invention to provide a washing machine having a reciprocating pounder which is also 1evolved during its reciprocating movement so that all of the cloth in the washing machine receptacle or tub will be uniformly acted on and thoroughly cleaned.

Vith the above and other objects in view the invention consists of a driving mechanismassetforthintheclaims andallequivalcnts thereof.

In the accompanying drawing in which the same reference characters indicate the samepartsinalloftheviews:Figure1 isa top view of the improved washing machine,

being broken away for clearness of illustration; Fig. 2 is a vertical sectional view' thereof taken on line of Fig. 1; Fig. 3 is a detail sectional view of the pounder portion of the machine taken on line3--3ofFig.2andonasmallerscale; Fig. 4 is a vertxl sectional view taken on line-ofFigS; Fig. isadetail view of the operating handle; Fig. 6 is a vertical sectional detail view of a modified form of pounder actuating mechanism; and Fig. 'i' is a similar view of another modification thereof.

Referring to the drawing the numeral 8 indicates a tub or receptacle which may be of the ordinary or of any improved type, and is provided with supporting legs 9 and a hinged cover 10. The improved washing machine actuating mechanism is mounted upon the cover and the crown or bevel gear l1 thereof has its hub portion l2 journaled mediallj' in the cover. A pinion 13 meshing with the gear 11 is mounted on a horizontal shaft 14. which is journaled in the bracket 15 carried by the cover. The outer end of the shaft 14 has iixedly mounted thereon a gear wheel 16 which is in mesh with a pinion l'iournaled on a stud shaft 18 promoting from the bracket beneath the horizontal shaft. A By wheel 19 al@ journaled on the stud shaft is xedly connected to and turns with the pinion 17 and is adapted to carry the actuating parts of the mechanism over dead centers and provide easy running of the parts.

The horizontal shaft 14 is rotated by means of a hand lever :20 ulcrumed on an extension 15 of the bracket or by other means and having a link connection :21 with a wrist pin 22 projecting from the outer face of the gear wheel 16. The link is con nected to the medial portion of the handle and the wrist. pin forms a cranked connection with the gear wheel 16 so that the oscil lation of the hand lever will rotate the horiv zontal gear 16.

The hub 12 of the bevel gear 11 is pre vided with a rectangular or square bore 23 through which slidahly extends the rectangular or squared portion 24 of the vertically ettending pounder shaft Q5. The lower end of the shaft 25 carries a pounder 26 and the upper end portion 24 of said shaft is round in cro@ section and is journaled in the upstanding arm 27 of the casing -28 which incloses the two gears 11 and 13.

An arm 29 journaled on the rounded portion of the vertical shaft a short distance above the upper end of the squared portion is held from moving endwise on the shaft by means of a collar 30 fixedly mounted v thereon. The outer end of the arm 29 has a ball and socket connection 31 with the outer end of cranked member 3-2 which has a hinged connection 33 with the inner end of the horizontal shaft 14 so that as the horizontal shaft is revolved it- Will reciprocate the vertical shaft and the pounder due to the ball and socket joint and the hinged connection between the two shafts While the vertical shaft is being reciproted it. will also be rotated by means of the bevel gear connection between the vertical and horizontal shafts. The bevel gears are so proportioned with relation to each other as to causethe vertical shaft to reciprocate a plu rality of times with each revolution thereof.

In order to provide for the pounder 26 acting equally upon the clothes during its revolution the pounder is formed of oppo sitely extending segmental portions 34 having outer rounded ends 35 which are of greater Width than the medial portion at the huh 36 so that. the outer ends will cover a greater area of clothes than the medial portion thus approximately engaging the clothes equally during its segmental like reciproca tions The width of the segmental portions bear a fixed relation to the number of reciprocations made during each revolution of the pounder so that the pounder will act upon all parts of the clothes. The pounder is constructed with a rece in its lower side to form an air chamber 37 so that when the pounder is pressed downwardly into the water and into engagement with the clothes the water will seal the chamber andthe downward preure of the ponnder will force the air and Water trapped in the lorr portion of the chamber through the clothes and clean the same. The pounder from the end portions upwardly mediallj' and at approximately its point is provided withanairinlet 'gSShafingaliall faire 39 therebeneath which sheld in a valve cage 40. The valve serves to close the open. 'mg during the downward movement of the plunger and during the upward movement permits the air to enter the chamber and prevents the pounder from pulling up the clothes.

In the modified form shown in Fig. 6 the crank l1 is lixedly connected to the horizontal shaft 14 and is provided with a ball 4Q on its cranked end which is adapted to play in the tubular arm 43 journaled on the vertical pounder shaft 24. The outer end of the tubular arm is of angular form to permit the free universal movementof :he connection during the operation thereof.

ln the form shown in Fig. 7 the cranked arm ll' is provided with a tubular portion 4l. and the outer end of the arm 43 is pro vided with a ball i5 which plats in the tubular portion of the crank arm in substantially the same manner as in the first modification described.

From the foregoing description it will be seen that the washing machine is of simple conrnction and is well adapted for the purpose described.
